About REF 2021
REF 2021 is the second assessment carried out under the Research Excellence Framework (REF), after the first in 2014.
REF is a framework designed to assess the quality of research being conducted at UK universities. It is undertaken by the relevant national research funding body, Research England in UCL’s case. Three elements are taken into consideration: the quality of outputs (publications, performances, and exhibitions), their wider impact beyond academia, and the environment that supports research.
As one of UCL’s 11 faculties, The Bartlett makes a significant contribution to the university's REF performance. The Bartlett is pleased to stand with UK built environment faculties in celebrating the vibrancy of our disciplines and the strength of our collective research endeavour around the world. We are the UK’s largest faculty of the built environment and REF 2021 has confirmed both our unique breadth, and excellence across this portfolio.
Key Highlights
- The Bartlett is where the UK’s most ‘World Leading’ and ‘Internationally Excellent’ built environment research is undertaken
- 91% of our research has been deemed ‘World Leading’ and ‘Internationally Excellent’
- The Bartlett is number one for Research Power in the built environment
